A NEW FUNGAL GLUKAN AND ITS PREPARATION

A NEW FUNGAL GLUKAN AND ITS PREPARATION

A new glukan is produced by oyster fungus (Pleurotus ostreatus). Said glukan is a homopolymer beta (1->3) glukan, which is substitued in the -0-6 position on each fourth anhydroglucose unit with glucose or disaccharides which contain the (1->6) or (1->4) bonding. The proportion or glucose t...

Zusammenfassung:A new glukan is produced by oyster fungus (Pleurotus ostreatus). Said glukan is a homopolymer beta (1->3) glukan, which is substitued in the -0-6 position on each fourth anhydroglucose unit with glucose or disaccharides which contain the (1->6) or (1->4) bonding. The proportion or glucose to disaccharide in the branches is 2:1. A process for preparing said fungal glukan is described. The glukan is isolated from fruit-body of oyster fungus. Nouveau glucane produit par le champignon Pleurotus ostreatus des huîtres. Ledit glucane est un glucane beta(1->3) homopolymère substitué en position -0-6 sur un motif anhydroglucose sur quatre ayant un glucose ou des disaccharides contenant la liaison (1->6) ou (1->4). Le rapport entre le glucose et le disaccharide dans les ramifications est de 2:1. On a également prévu un procédé de préparation dudit glucane fongique. On isole le glucane à partir du corpuscule reproducteur du champignon des huîtres.
